Light Meter Project - Making Dfrobot Unihiker K10 Work with Standard Arduino Libraries
Pavleski Aug 22,2025
 The other day I received a shipment with a UNIHIKER K10 development board from DFRobot, which I received as a prize. The device is excellently packaged in a branded box, protected from damage during transportation. I immediately asked for information because I have no experience with this development board so far. In fact, the device is based on an ESP32-S3 Xtensa LX7 microcontroller and an ILI9341 TFT display with a resolution of 320x240 pixels. The display is protected by a metal fr...

STM32F429 TFT DCMI v1.0
Mackey Aug 17,2025
STM32F429 DCMI & FMCSupports a 3.5" 16 bit parallel TFT display via FMC, and 8 bit OV5640 camera via DCMI.Note that this board doesn’t have any SRAM other than the SRAM on the STM32F429. This means that the camera data stream must be processed as it’s received.This board was designed to implement a key reader as an accessory for my key code cutter machine. This board works with my OV5640 Camera board.For more information about this board and the Key Reader project follow the link h...

DIY Simple Arduino Whack-a-Mole Game
Pavleski Aug 15,2025
 A "Whack-a-Mole" game is a classic arcade-style game where moles pop up randomly from holes, and the player uses a mallet or similar tool to "whack" the moles before they disappear. The goal is to hit the moles as they appear, to score points while avoiding hitting any other targets. It’s typically timed and the game ends after a certain period, with the player's score displayed. This time I will present you a simple way to make a Whack a mole portable game using an Arduino microcontr...

5-way navigator PCB
Curious Scientist Aug 15,2025
In this article, I show you a genius way of handling multiple buttons with a microcontroller. I “discovered” this method when I got my Hawkeye Firefly Split V6 PRO camera and used its remote controller. The remote controller has 5 buttons, but there are only two cables coming from it. This made me curious; therefore, I reverse-engineered the circuit and studied its working principles. Below, I will show you everything about the circuit, and I will explain how you can make your own circuit based ...
